leaking fuel *help*

Good news / Bad news

The tank is back on. No leaks. So this was not much of a learning experience. Cant explain why pulling the bowls would have gone from "serious leak" to "back to normal".

Oh well, thanks again guys for the conversation.......

I hate when that happens! Sure, you got it fixed but aren't sure what you did to fix it. Remember, when it doubt, ALIENS!

And thank you for the set of gauges you sent me (on your own dime) for big Suzi about seven years ago. I'm working to bring her home now.

So..... 20 days ago it was not dripping a drop. Really have not started it since. Today, Dripping again like a leaky rain gutter ! Yes, The petcock is working. only drips on PRI. Im gonna rule out the T cause the drips appear to start above it and the new hose. Looks like its somewhere above the bowls or even the intake tubes. You can kinda see in the vid its even on the front rail (angle?) Frustrating !! I rode it for about 10 minutes but it didnt slow down.....

Fuel Tee and/or fuel transfer tube O-rings would be my guess. The O-rings on those parts come into contact with outside air and petrify after 30 years. They swell when gas comes in contact with them which is why they stopped leaking before but started again 30 days later.

I guess I got an extra 9 years outta them . Wanna re-build them ?

I had the tank off anyway so I ran about 6oz of straight seafom into the carbs then shut it off overnight. Tonight after work I went for a ride to burn the seafoam out and when I got back (15min) ..........no leaks.

That video looks just like the carbs leaking on my CB1100F after sitting for the winter or a few weeks. but so far, after 20 min. or so they stop until it sits long enough for the "O" rings to dry out again. As long as it gets started every few wks. no leak, guessing keeping the "O" rings wet is a solution, not really the fix. Couldn't promise that is the problem as I haven't fixed it, but just haven't come up with any other ideas.
